Low clouds 1

Low clouds are Nimbostratus, Stratus, Stratocumulus, Cumulus and Cumulonimbus. Nimbostratus clouds are dark and quite homogeneous clouds. These clouds are associated with heavy downpours, high winds and sea conditions that are hazardous for small vessels. Take precautions when Nimbostratus clouds are in sight. Stratus clouds are gray, thin and usually featureless. These clouds bring fine drizzle or snow grains, and in certain conditions, fog.
Stratocumulus clouds can cover part or all of the sky. Sometimes some holes in the cloud deck can be observed. These clouds usually produce light rain or snow. Stratocumulus clouds that have been formed from degenerating cumulus clouds usually indicate fair weather. Visibility may be reduced when precipitation occurs.
